  Unit 6: Parental care

  • Refers to looking after young ones through feeding, keeping them warm, protecting them from the predators
    
  • Such animals give rise to few offspring.

  Subject methodology

  Take note of the following important points when teaching this topic:

  • Learners must understand the link between reproduction and the continuation of the species
  • There are several strategies that animals use to ensure successful reproduction so that the species can endure
  • Learners must have a clear understanding of the terminology in order to study reproductive strategies
  • Although this topic only has a few marks in the exam, the type of questions are not always linked to terminology. In recent years, data-based questions based on this topic have been included in exams and therefore it is important that learners know and understand the concepts and can apply this knowledge in case studies
    
  • The main types of questions based on this topic include:
  • Terminology
  • Amniotic egg
  • Courtship behaviours
  • Types of reproduction.

• Enrichment resources

  We have sourced the following online resources - can you find more and add them to your collection?

  Module summary

  Vertebrates have developed various reproductive strategies and the study of these strategies enable learners to explain why certain strategies ensure survival of the species in the environment they occur in.
  

  In order to understand this topic, learners must know the following concepts:  internal and external fertilization, ovipary, ovovivipary, vivipary, precocial and altricial development, the amniotic egg and parental care.
